Definitions
- the field of disclosure relates generally to electronic gaming, and more particularly to systems and methods for providing a metamorphic reel game feature in electronic games.
- EGMs Electronic gaming machines
- gaming devices provide a variety of wagering games such as slot games, video poker games, video blackjack games, roulette games, video bingo games, keno games and other types of games that are frequently offered at casinos and other locations.
- Play on EGMs typically involves a player establishing a credit balance by inputting money, or another form of monetary credit, and placing a monetary wager (from the credit balance) on one or more outcomes of an instance (or single play) of a primary or base game.
- a player may qualify for secondary games or bonus rounds by attaining a certain winning combination or triggering event in the base game. Secondary games provide an opportunity to win additional game instances, credits, awards, jackpots, progressives, etc.
- Awards from any winning outcomes are typically added back to the credit balance and can be provided to the player upon completion of a gaming session or when the player wants to “cash out.”
- “Slot” type games are often displayed to the player in the form of various symbols arrayed in a row-by-column grid or matrix. Specific matching combinations of symbols along predetermined paths (or paylines) through the matrix indicate the outcome of the game. The display typically highlights winning combinations/outcomes for ready identification by the player. Matching combinations and their corresponding awards are usually shown in a “pay-table” which is available to the player for reference. Often, the player may vary his/her wager to include differing numbers of paylines and/or the amount bet on each line. By varying the wager, the player may sometimes alter the frequency or number of winning combinations, frequency or number of secondary games, and/or the amount awarded.
- Typical games use a random number generator (RNG) to randomly determine the outcome of each game.
- RTP random number generator
- the RTP and randomness of the RNG are critical to ensuring the fairness of the games and are therefore highly regulated.
- the RNG randomly determines a game outcome and symbols are then selected which correspond to that outcome.
- some games may include an element of skill on the part of the player and are therefore not entirely random.
- an electronic gaming system in one aspect, includes a main display configured to display a wagering game comprising a plurality of adjacent spinnable reels, each spinnable reel being virtual and having a plurality of adjacent game symbol positions.
- the electronic gaming system also includes a player input interface configured to receive a player input.
- the electronic gaming system further includes a random number generator.
- the electronic gaming system also includes a credit input mechanism.
- the credit input mechanism includes at least one of a ticket reader, a bill acceptor, and a coin input mechanism.
- the credit input mechanism is configured to receive a physical item representing a monetary value for establishing a credit balance used for a credit wager.

- the electronic gaming system further includes a tangible, non-transitory, computer-readable storage medium having instructions stored thereon.
- the electronic gaming system also includes a game controller communicatively coupled to the display, the player input interface, the random number generator, the credit input mechanism, and the tangible non-transitory computer-readable storage medium.
- the game controller Upon execution of the instructions, the game controller is configured to initiate play of the base game upon receipt of the credit wager and a player input from the player input interface, thereby causing a simulated spinning of the plurality of adjacent spinnable reels.
- the game controller is also configured to change the base game to a metamorphic reel game.
- the game controller is further configured to create a morphed reel based on symbols included in a first and a second reel of the plurality of adjacent spinnable reels.
- the game controller is also configured to replace the first and the second reel with the morphed reel in the metamorphic reel game during the simulated spinning.
- the game controller is further configured to determine a metamorphic reel game outcome based on a metamorphic reel game paytable and a reduced number of reels including the morphed reel.
- the game controller is also configured to award credit to the player based on the metamorphic reel game outcome.
- a method of electronic gaming is provided.
- the method is implemented using a gaming system.
- the gaming system includes a main display configured to display a wagering game.
- the gaming system also includes a player input interface.
- the gaming system further includes a credit input mechanism.
- the credit input mechanism includes at least one of a ticket reader, a bill validator, and a coin input mechanism.
- the credit input mechanism is configured to establish a credit balance that is increasable and decreasable based on wagering activity.
- the gaming system also includes one or more tangible, non-transitory, computer-readable memory devices.
- the gaming system further includes one or more processors communicatively coupled to the one or more memory devices.
- the method includes initiating play of a base game upon receipt of a credit wager and a player input from the player input interface, thereby causing a simulated spinning of a plurality of adjacent spinnable reels.
- the base game includes the plurality of adjacent spinnable reels. Each reel has a plurality of circumferentially adjacent game symbol positions.
- the base game uses a base game paytable.
- the method further includes spinning the reels.
- the method also includes initiating a metamorphic reel game, the metamorphic reel game using a metamorphic reel game paytable.
- the method further includes morphing a plurality of reels into a lesser number of reels during a simulated spinning by combining symbols from a first reel and symbols from a second reel to form a single resultant reel having the combined symbols.
- the method also includes stopping the reels in an order specified by the initiating.
- the method further includes determining a metamorphic reel game outcome using a metamorphic reel game paytable and the single morphed reel.
- the method also includes awarding credit to the player based on the determined metamorphic reel game outcome.
- one or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon When executed by at least one processor, the computer-executable instructions cause the processor to initiate a base slot game having a plurality of slot reels comprising adjacent game symbol locations. The instructions also cause the processor to randomly initiate a metamorphic reel game prior to determining a base slot game outcome. The instructions further cause the processor to morph at least two slot reels of the plurality of slot reels into a single morphed slot reel during a simulated spinning. The instructions also cause the processor to determine a metamorphic reel game outcome based on the single morphed slot reel and the remaining unmorphed slot reels. The instructions further cause the processor to award credit to a player based on a metamorphic reel game paytable. The metamorphic reel game paytable is different than a base slot game paytable.

- FIG. 6 is a view of the gaming display area shown in FIG. 1 illustrating a symbol rank-based morphing process.
- FIG. 7 is a flow chart of a method of electronic gaming implemented using a gaming device.
- Embodiments of the gaming systems, gaming devices, and methods described herein provide an electronic gaming machine or gaming device that includes a main display on which a wagering game is displayed during game play.
- the wagering game is of the slot-type game that includes a plurality of adjacent spinnable reels (typically five or three reels) that each have a plurality of game symbol positions that are adjacent about the circumference of the respective reel.
- the reels and game symbol positions form a grid on the main display.
- the electronic gaming device includes a controller that is operable to initiate play of the base game upon receipt of a credit wager and a player input from a player input interface. The controller selects a symbol from a set of symbols for each of the plurality of adjacent game symbol positions.
- each game symbol position typically only one symbol is positioned within each game symbol position, however a plurality of game symbols may be positioned inside a single game symbol position. For example, by overlaying two or more game symbols one on top of each other, combining two or more game symbols into a new symbol, positioning game symbols side-by-side in a single game symbol position, or combinations thereof.
- Each symbol may have one of a plurality of associated ranks wherein each rank influences a game outcome differently than each other rank.
- the controller spins the reels, receives an output from the random number generator, and stops the reels in an order specified by the received output.
- the controller determines a base game outcome based on a base game paytable and a payline that starts with the reel that stopped first. If an interior reel between the rightmost and leftmost reels stops first, the controller enters a metamorphic reel game.
- the game controller morphs a plurality of reels of the plurality of adjacent spinnable reels into a single reel. For example, a base game having five reels may have two reels morphed together into a single reel to form a four reel game, or may have four reels morphed into two reels forming a three reel game. Other combinations of morphing reels are implemented based on the output from the random number generator.
- the controller determines an outcome of the metamorphic reel game using a metamorphic reel game paytable and the morphed reels, and award credit to the player based on the determined metamorphic reel game outcome.

- FIG. 3 is a block diagram of electronic gaming device 104 including a metamorphic reel feature.
- electronic gaming device 104 includes gaming display area 118 configured to display a wagering game including a plurality of spinnable reels 130 adjacent to each other in a lateral direction 302 , each spinnable reel 130 has a plurality of game symbol positions 304 adjacent to each other in a circumferential direction 306 .
- a base game instance 307 of gaming display area 118 illustrates a five reel base game and a metamorphic game instance 309 illustrates a three reel metamorphic reel game after the morphing process is completed.
- Electronic gaming device 104 also includes a player input interface or button deck 120 configured to receive a player input, a random number generator 212 (shown in FIG. 2 ) configured to facilitate game play, with respect to game outcomes and game events, such as, initiation of a bonus games, such as, but not limited to a metamorphic reel game, described in detail below.
- Electronic gaming device 104 further includes a credit input mechanism including at least one of a ticket reader 224 , a bill acceptor/validator 234 , and a coin input mechanism, the credit input mechanism is configured to receive a physical item or a wireless signal representing a monetary value for establishing a credit balance used for a credit wager that is used to initiate play of a base game.
- Electronic gaming device 104 also includes a tangible, non-transitory, computer-readable storage medium, for example, memory 208 (shown in FIG. 2 ) having instructions stored thereon.
- Game controller 202 is communicatively coupled to gaming display area 118 , main display 128 , button deck 120 , random number generator 212 , credit input mechanisms ticket reader 224 , a bill acceptor/validator 234 , and memory 208 .
- Game controller 202 upon execution of the instructions, is configured to initiate play of the base game upon receipt of the credit wager and a player input from the player input interface or button deck 120 .
- Game controller 202 selects a symbol from a set of symbols for each of the plurality of adjacent game symbol positions 304 .
- each symbol has one of a plurality of associated ranks, each rank influences a game outcome differently than each other rank.
- Game controller 202 is configured to spin reels 130 , receive an output from random number generator 212 , and to stop reels 130 in an order specified by the received output.
- electronic gaming device 104 determines a base game outcome based on a base game paytable and a payline that starts with the reel that stopped first. For example, if the rightmost reel 130 stops first, the outcome is determined based on a right to left payline in the base game paytable. If the leftmost reel 130 stops first, the outcome is determined based on a left to right payline in the base game paytable.
- game controller 202 triggers a metamorphic reel game wherein the game controller 202 morphs a plurality of reels 130 of the plurality of adjacent spinnable reels 130 into a single morphed reel 312 .
- three reels 130 may be morphed into one or two reels 312 .
- the leftmost reel 308 is morphed into a single reel 314 with the reel immediately adjacent to the leftmost reel, reel 310 .
- the rightmost reel 316 is morphed with the reel 318 immediately adjacent rightmost reel 316 to form a rightmost morphed reel 320 .
- a three reel game 324 is formed. Accordingly, a three reel game paytable is used to award a winning outcome of the three reel game 324 .
- the paylines of the three reel game 324 are different than (e.g., less in number) the paylines available in the five reel game. In various embodiments, the paylines of the three reel game 324 pay higher awards than the paylines of a five reel game.
- game controller 202 determines the metamorphic reel game outcome using the metamorphic reel game paytable, unmorphed reel 322 , and morphed reels 314 and 320 , and awards credit to the player based on the determined metamorphic reel game outcome.
- symbol rank of the initial symbols on the pre-morphed reels 130 affects the morphing results. More specifically, and for example, the game controller 202 identifies the adjacent reels 308 and 310 for morphing. For each symbol position on reels 308 , 310 (e.g., for each row), game controller 202 compares laterally adjacent symbols (e.g., one from each reel 308 , 310 in that row) to determine a single morphed symbol to be used in the associated symbol position on the morphed reel 314 . More specifically, game controller 202 selects the highest ranking symbol from the adjacent symbols and uses that highest ranking symbol on the morphed reel 314 .
- game controller 202 may morph an “7” symbol from reel 308 and a laterally adjacent “diamond” symbol from reel 310 into a “diamond” symbol on the morphed reel 314 because “diamond” is a higher-ranked symbol than “7.”
- game controller 202 identifies the highest-ranked symbol of the set and places that highest-ranking symbol into the associated symbol position on the morphed reel 312 .
- the resulting morphed reel 314 is likely to have an increased average symbol rank, and thus is more exciting to the player.
- placing may be used herein, in some contexts, to describe an operation involving selecting a symbol to populate onto a morphed reel (e.g., morphed reel 312 ).
- a morphed reel e.g., morphed reel 312
- two laterally adjacent symbols from the pre-morphed reels 130 may be said to be “replaced” by the higher-ranked of those two original symbols when the higher-ranked symbol is added onto the morphed reel 312 .
- the symbol being added to the morphed reel 312 may be replacing either or both of the original symbols.
- game controller 202 may morph two or more adjacent reels 130 into a morphed reel 312 by replacing one or more sets of laterally adjacent symbols with at least one special metamorphic reel game symbol.
- first reel 308 and second reel 310 of the plurality of adjacent spinnable reels 130 may be morphed into single reel 314 while first reel 308 and second reel 310 are spinning at approximately equal speeds and may stop spinning as morphed reel 314 .
- game controller 202 may synchronize the rotational speeds of the reels 308 and 310 and display an animation of the reels 308 , 310 collapsing into merged reel 314 before the spinning stops.
- reels 308 and 310 may spin a slower rate while morphing than in base game instance 307 so the player is able to visually witness the details of the morphing process, thereby providing enhanced excitement and understanding of the morphing process.
- Game symbols used in determining game outcomes are displayed in the plurality of adjacent game symbol positions 408 in a one-to-one correspondence. In some other embodiments, more than one game symbols are displayed in at least one of the plurality of adjacent game symbol positions.
- FIG. 4 is a front view of gaming display area 118 in a base game instance 402 and in a metamorphic reel game instance 404 .
- base game instance 402 may be similar to base game instance 307
- metamorphic game instance 404 may be similar to metamorphic game instance 309 .
- a metamorphic reel game is a slot-type wagering game where, during play of a base game, a metamorphic feature is initiated (e.g., randomly, or upon occurrence of a triggering condition).
- the metamorphic feature transitions from a multi-reel base game to a metamorphic reel game where the number of reels has been reduced and a metamorphic reel game paytable is used (e.g., based on the remaining number of reels).
- a metamorphic reel game paytable is used (e.g., based on the remaining number of reels).
- five laterally adjacent reels 406 are displayed.
- Each reel 406 has a plurality of circumferentially adjacent game symbol positions 408 .
- This example configuration of reels 406 and game symbol positions 408 is associated with a five-reel paytable stored in one or more memory devices 208 communicatively coupled to one or more processors 204 .
- the initial five reels transition to a lesser number of reels and the metamorphic reel game paytable is used.
- five reels 406 have been reduced to three metamorphic reel game reels 410 . Reducing the five reels 406 to three reels 410 is accomplished by morphing two or more reels 406 into a lesser number of reels 410 .
- the two leftmost reels 412 and 414 in base game instance 402 referred to as morphing reels, have been morphed into a single leftmost reel 416 in metamorphic reel game instance 404 and referred to as a morphed reel.
- any two or more reels 406 may be morphed into any lesser number of reels 410 .
- reels 414 and a reel 418 may be morphed into a single morphed reel 420 .
- reels 414 , 418 , and a reel 422 may be morphed into two morphed reels, for example, reels 416 and 420 , or reels 414 , 418 , and a reel 422 may be morphed into a single morphed reel, for example, reel 420 .
- the morphing process is accomplished in any of a plurality different ways as described in detail below. While no symbols are shown in metamorphic game instance 404 , it should be understood that morphed reels 410 are created (e.g., populated with symbols) by game controller 202 based on one of the morphing processes described herein.
- the metamorphic feature is triggered randomly (e.g., based on a result of a random number generator).
- the metamorphic feature may be triggered based the result of a stopped reel 406 (e.g., as a trigger condition). For example, during a spin, some reels 406 may stop while other reels 406 continue to spin.
- the metamorphic feature may be triggered based on the occurrence of a particular symbol (e.g., one or more triggering symbols, such as three “coins”) on the stopped reel 406 . As such, two reels 406 that are still spinning may be merged based on the occurrence of the triggering symbol on the stopped reel 406 .
- the metamorphic feature may be triggered based on the result of a previous spin. For example, if the triggering symbol appears in a first spin (e.g., without having activated the morphing feature), then the metamorphic feature may be triggered during a second spin. The player may be subject to an additional wager to activate the metamorphic feature in the second spin, or the metamorphic feature may be granted in the second spin during a free spin.
- FIG. 5 is a view illustrating an alternating symbol morphing process.
- a symbol pattern 500 of multiple game symbols 502 are displayed on multiple game symbol strips 504 that correspond to symbols 408 on reels 406 .
- symbol pattern 500 includes, for example, five game symbol strips 504 .
- symbol pattern 500 includes, for example, three game symbol strips 508 .
- symbols 502 from a pair of morphing strips 510 and 512 , or 514 and 516 are combined into morphed strips 518 and 520 , respectively.
- the morphing process alternates game symbols 502 from each associated strip 510 and 512 , or 514 and 516 in each pair of strips to form morphed strip 518 or 520 .
- the alternating symbol morphing process is sometimes referred to as a “zipper” merge, or interdigitating, because game symbols 502 alternate in morphed strips 518 and 520 similar to the teeth on a zipper.
- morphing strip 510 includes the odd numbers between 1 and 17, and morphing strip 512 includes the even numbers between 2 and 18.
- game controller 202 selects symbols 502 from each separate morphing strip 510 , 512 in an alternating fashion. For example, “1” is added to morphed strip 518 from morphing strip 510 , “2” is added to morphed strip 518 from morphing strip 512 , “3” is added to morphed strip 518 from morphing strip 510 , “4” is added to morphed strip 518 from morphing strip 512 , and so forth.
- FIG. 5 illustrates a partially morphed section 404 of morphed strip 518 (e.g., with “1” through “4” already added to morphed strip 518 ) and remaining unmorphed sections 402 of morphing strips 510 and 512 (e.g., with “5” through “17” on morphing strip 510 and “6” through “18” on morphing strip 512 ).
- FIG. 6 is a view of gaming display area 118 illustrating the symbol rank-based morphing process described above in reference to FIG. 3 .
- game symbols 304 on morphing reel 308 that are of superior rank to a laterally adjacent game symbol 304 on morphing reel 310 becomes the game symbol 304 on morphed reel 312 .
- a diamond symbol 602 and a “7” symbol 604 are laterally adjacent at the top position of morphing reel 308 and morphing reel 310 , respectively.
- diamond symbol 602 has a superior rank to “7” symbol 604 . Consequently, diamond symbol 602 is positioned at the top position on morphed reel 314 as it supersedes “7” symbol 604 .
- a bar symbol 606 out ranks a cherry symbol 608 , so similarly, bar symbol 606 is positioned in the middle position on morphed reel 314 .
- diamond symbol 602 outranks “7” symbol 604 so diamond symbol 602 is placed in the bottom position on morphed reel 314 .
- a center reel 610 is unmorphed in this example, so it is unchanged in second instance 309 from first instance 307 .
- Morphing reels 612 and 614 in this example, yields morphed reel 320 .
- Diamond symbols 602 and “7” symbol 604 each outrank their adjacent symbol illustrated in reels 612 and 614 resulting in diamond symbols 602 in the top and middle positions of reel 320 and “7” symbol 604 in the bottom position.
- a three reel paytable stored in memory 208 is used to determine an award to be credited to the player's account.
- game symbols 408 may be combined during the morphing process.
- identical game symbols 408 may be combined together during the morphing process. For example, when identical game symbols 408 are laterally adjacent to each other on two reels that are to be morphed together, or otherwise would end up adjacent to each other on the morphed reel, the morphing process may combine those identical game symbols 408 into a double symbol (e.g., two diamonds combining into a “2 ⁇ ” diamond). Similarly, two adjacent “2 ⁇ ” diamonds may be combined into a “4 ⁇ ” diamond during the morphing process. For another example, two top box wheel spin symbols may combine during the merging process to award the player with two free spins.
- some non-identical but related game symbols 408 may be combined during the morphing process.
- a diamond and a “2 ⁇ ” diamond may be combined into a “3 ⁇ ” diamond during the morphing process (e.g., related based on the underlying symbol, diamond).
- an Ace being adjacent to a Jack may be combined, during the merging process, to generate a “Blackjack” symbol on the merged reel.
- not all identical game symbols 408 are combined during the morphing process, even if they are adjacent.
- diamonds may be identified as combinable, and cherries may not be combinable. As such, adjacent diamonds may be combined during the morphing process, where adjacent cherries will not be combined.
- Adjacency between two symbols may include the two symbols being laterally adjacent to each other on two reels that are to be merged (e.g., laterally adjacent before merging) and two symbols being adjacent to each other on the merged reel (e.g., during or after the merging).
- Spaces 616 and 618 are made available on gaming display area 118 .
- Spaces 616 and 618 may be used to display additional information, instructions, graphics, or combinations thereof to the player.
- a width of reels 314 , 322 , and 320 may be increased to fill the available spaces 616 and 618 .
- the metamorphic feature may include a visual display highlighting the morphing process. For example, in some embodiments, if the metamorphic feature involves dropping lower-ranked symbols in favor of higher-ranked symbols, a higher-ranked symbol may be displayed as bumping or pushing a lower-ranked symbol off of the merged reel, “squishing” the lower-ranked symbol, or ghosting the higher-ranked symbol over the lower-ranked symbol and fading away the lower-ranked symbol. In some embodiments, combining two symbols may be displayed as squeezing two individual symbols together to generate a combined symbol (e.g., two diamonds pressing together to form a “2 ⁇ ” diamond, perhaps with a fluid morphing effect). Such visual display may provide heightened excitement to the player, and may serve to illustrate the priority of certain symbols over others.
- a visual display may provide heightened excitement to the player, and may serve to illustrate the priority of certain symbols over others.
- the metamorphic feature may include replicating one or more morphed reels 312 (e.g., after two reels 130 have been morphed into a morphed reel 312 ).
- morphed reel 314 may be duplicated and be presented as a fourth reel 312 (not shown in FIG. 6 ) in the metamorphic game instance 309 (e.g., to the right of morphed reel 314 , between morphed reel 314 and unmorphed reel 322 .
- both morphed reels 314 and 320 may be replicated as such, thereby changing the metamorphic game instance 309 back to a five reel game.
- FIG. 7 is a flow chart of a method 700 of electronic gaming implemented using a gaming device.
- the gaming device includes a main display configured to display a wagering game, a player input interface, a credit input mechanism including at least one of a ticket reader, a bill validator, and a coin input mechanism.

- method 700 may include stopping reel 5 and then reel 1 at operation 710 , determining a game outcome via a right to left evaluation of a five reel pay table at operation 712 , and awarding credit to the player based on the game outcome (e.g., based on the 5 primary game reels).
- Method 700 also includes morphing a plurality of reels (e.g., the five primary game reels) into a lesser number of reels by combining symbols from a first reel and symbols from a second reel to form a single resultant reel having the combined symbols.
- morphing the reels includes slowing the spinning speed of reels 1 and 5 at operation 722 and accelerating the spinning of reels 2 and 4 to match the speed of reels 1 and 5 at operation 724 .
- Method 700 then includes, at operation 726 , merging reel 1 and reel 2 into a morphed reel 1 that is displayed to the left of primary game reel 3. Further, method 700 includes, at operation 728 , merging reels 4 and 5 into a morphed reel 3 that is displayed to the right of primary game reel 3. As such, the metamorphic game then includes morphed reel 1, the original primary game reel 3, and morphed reel 3, left to right. At this stage, post-morphing, morphed reels 1 and 3 may continue to spin. As such, morphed reels 1 and 3 may then be stopped at operation 730 .
- Method 700 further includes determining a metamorphic reel game outcome using a metamorphic reel game paytable (e.g., a three reel pay table) and the morphed reel(s) at operation 732 and awarding 714 credit to the player based on the determined metamorphic reel game outcome.
